摘要
本课题涉及不同结构的支架结构的设计、制造和表征，使用聚乳酸(PLA)长丝，通过熔融沉积建模(FDM)制造微骨结构。选择这种形态是因为它具有良好的强度，高孔隙率导致良好的营养物质和废物扩散，以及良好的力学性能。通过对每一种材料进行压缩试验获得载荷与位移值，作为研究的总体结果，确定了具有更好力学性能的微观结构来替代受损的骨组织。增材制造(AM)，或3D打印，使用3D建模数据逐层构建对象。增材制造已经从快速原型到直接生产的工具进行了探索。更重要的是，增材制造可以与CAM(计算机辅助制造)、CNC(计算机数控)和CAD(计算机辅助设计)集成，用于3D打印对象。增材制造的应用范围广泛，从生物医学应用到飞机设计，并且正在慢慢探索在石油和天然气行业的应用。用于增材制造的材料包括聚合物、金属、陶瓷和复合材料，然而，用于增材制造的材料仍然有限。增材制造有可能在降低成本和浪费的情况下设计具有复杂结构的产品，还可以减少与文件和生产计划相关的管理费用。与传统技术相比，增材制造技术使用更少的材料生产零件，并对备件需求提供快速响应。增材制造与传统制造不同，它是通过逐层添加原材料来制造零件的。不同的增材制造技术已经被发明出来，其中最流行的是立体光刻(STL)，熔融沉积建模(FDM)，选择性激光烧结(SLS)，三维打印(3-DP)。无论增材制造技术的类型如何，一般来说，任何增材制造技术都涉及相同的基本步骤，从虚拟CAD描述到物理部分。对于在产品开发过程的早期阶段实现的产品，遵循这些步骤，因为在此阶段，部件可能只需要粗略的估计。[3]张建军，张建军，张建军，等。在工艺的后期阶段，零件可能需要后处理(如喷砂、表面处理和喷漆等)。化工学报，2020,13(1):181-186。DOI= http://dx.doi.org/10.20902/IJCTR.2019.130122 International Journal of ChemTech Research CODEN (USA): IJCRGG, ISSN: 0974-4290, ISSN(Online):2455-9555 vol .01, pp 181-186, 2020 N.

Experimental Investigation of Mechanical Behavior in 3D
Printed PLA Triply Periodic Minimal Surface Structure for
Orthopedics
This project is related to the design, fabrication and characterization of scaffold structures of different structure Using Polylactic Acid (PLA) filament, the micro bone structures are manufactured by Fused Deposition Modeling (FDM). Such morphology is chosen for its good strength, high porosity leading to good nutrient and waste diffusion, and favorable mechanical properties. Load vs Displacement values are obtained by taking compression tests for each as an overall outcome of the research, microstructure with better mechanical properties to replace the damaged bone tissues is identified.
